SPECIFICATION forming part Of Letters Patent No. 686,595, dated November 12, 1901. Application filed March 13,1901. Serial No. 50,899- (No model.)

To all whom it may concern.-

Be it known thatI, JOSEPH W. GUs'HMAN,

a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Devices for Applying Metallic Seals to Envelops, of which the following is a specification.

The object of this invention is to provide a convenient and eifective device by which the closing-flap of an envelop may be permanently securedto the subjacent parts of the envelop by a metallic seal, thus rendering it impossible to tamper with the envelop-seal without tearing and disfiguring the envelop.

In the accompanying drawings, Figure 1 is a perspective view showing an envelop and the device for applying the metallic seal in piece of sheet metal with the part A and is turned up thereto at right angles, as shown. A vertically-rocking hammer-arm C is formed with a hub C, the outer end of which is fully open and the inner end of which is partly closed by an inwardl -projecting flange c, as shown. A rivet-bolt has a large head which covers the outer edgeof the hub and a shoulderd, that fits in the opening of the hub.

The other end of the rivet occupies the small opening formed by the above mentioned flange, and its reduced end d passes through an aperture in the handle part B and is up- I A spiral spring enveloping the rivet within the hub has one end attached to the flange c and its opposite end to the shoulder d of the rivet-bolt." The reaction of the spring is such as to hold the arm elevated. A segmental notch c', as shown by dotted lines in Fig. 3, is cut in the inner or rear face of the in the tubular part E E from its edge.

hub C, and a pin 0 secured in the handle 'part' B, projects intosaid notch and limits the upward movement of the arm 0.

On the outer end of the arm 0 is a tubular part of larger diameter at its lower end E than it is at its upper part E, the two parts being separated by an inwardly-projecting flange-e.

A seal or staple-driving hammer is contained and is constructed as follows: It has a head F, which abuts against the under face of the flange e, and a shank f, screw-threaded at its end and seated in the knob G. Between the knob G and the flange e a spiral spring f is disposed around the shank. In the under face of the knob Gr, concentric with the shank f and concentric with the axis of the tubular part E E, is a deep circular slot 9. When the knob is struck and the hammer F driven downwardly, the part E-.passes into said slot.

Fig. 4 shows a suitable disk seal made of metal and having any suitable number of sharpened teeth projecting at right angles It is preferably of such size as to fit into the opening'of the part E spiii; ciently tight'to be held therein.-.-:- When ,therefore,the device is applied in position, as shown in Fig. 1, and the envelop-flap'closed, the arm C may be pressed down into contact with the flap and a sharp blow delivered upon the knob to cause the teeth of the seal to pass through the thicknesses of paper and be turned or clenched beneath them. Of course the seal may be placed upon'the envelop-flap and the arm 0 pressed down, so that the part E will inclose the seal. Either way of using the seal would be convenient.-

This device may also be used as a stapler to fasten together sheets of paper.

I claim as my invention- 1. In an envelop metallic-sealing device, the combination of the part A having a depression A at its end, a handle part B turned up at right angles to the part A, a vibrating arm having a hub 0 attached to the part B by a rivet-bolt, the spiral spring surrounding the bolt inclosed within the hub and normally tending to elevate the vibrating arm, the tubular part E E of two ,difierent diameters at the end of the vibrating arm, the hammer F seated therein, its shank,the knob G, to which the shank is attached and the spiral spring surrounding the shank and located within the part E.

2. In an envelop metallic-sealing device, the 5 combination of the part A having a depression A at its end, a handle part B turned up at right angles to the part A, a vibrating arm having a hub 0' attached to the part B by a rivet-bolt, the spiral spring surrounding the to bolt inclosed within the hub and normally tending to elevate the vibrating arm, the tubular partE E of two diflferent diameters at the end of the vibrating arm, the hammer F seated therein, its shank, the knob G having the'annular slot g, towhich the shank is at 1g tached and the spiral spring surrounding the shank and located withinthe part E. I

In testimony whereof I have hereunto subscribed my name JOSEPH W. CUSHMAN.
